Turn Claude Code into your personal operating system

Most people use AI as a chatbot. The bigger unlock is building small systems that run on a schedule. Each of these is a slash command plus a subagent, stored in your repo.

The pattern is always the same: a command in .claude/commands/, a specialist in .claude/subagents/, and a folder where the output accumulates so it can be compared over time.

1. Daily brief (morning)

A /daily-brief command that reads your files to work out what you actually care about, then web-searches only the last 7 days, includes publication dates, and explains why each story matters to you. Two subagents: one that infers your interests, one that curates and verifies dates. The date filter is the important part — without it you get made-up or stale news.

2. Daily check-in (evening)

A /daily-checkin command that asks the same seven questions every night: mood out of 10, three things you got done, tomorrow’s one priority, energy level, blockers, what you’re grateful for, and anything else. Saves to journal/daily/YYYY-MM-DD.md, then a reflection subagent reads the last few days and shows you mood and energy trends you can’t see yourself.

3. Weekly check-in

A /weekly-checkin that reads your project context first and works out which metrics matter for you — followers and views for a creator, MRR and churn for SaaS, commits and stars for a developer — instead of using a generic template. Then it asks for those numbers, compares them to last week from metrics/metrics-history.md, and writes a report with growth percentages.

4. Brain dump analyser

Write messy, unstructured thoughts into braindumps/. A /brain-dump-analysis command runs an extractor that finds recurring themes, tracks how your thinking changed over time, and pulls out the questions you keep circling — using your own words. Then an analyst turns that into action items, and for creators, content ideas.

5. Newsletter researcher

A /newsletter-research command that reads the newsletters you and your competitors publish, finds what’s trending and what nobody has covered, then writes three subject lines and a full 500–800 word draft in your voice — not an outline.

Why this works

The intelligence isn’t in the prompt, it’s in the discovery step. Every one of these reads your existing files before it asks you anything, so it adapts instead of handing you a template. Start with one. The daily check-in is the easiest and you’ll feel it within a week.
